A noun used to describe the utter decay of the mental state, usually due to alcohol or marihuana. One who has hit "the abyss" usually ends up being ill, depressed, fubar, or otherwise in a "deep dark place"

That last hit sent richard straight to the abyss, he's in the corner cuddling with some shoes!

The most emo word ever. Abyss grew up as a charming young boy, used only to describe deep pits that you would rather not fall into. However, as time progressed, Abyss began to associate with more "hardcore" words. He also began wearing Tokio Hotel T-shirts and dying his hair black. This is presumed to be a result of his parents' troubled relationship when he was young. He is frequently seen with his friends "Deep", "Pitiful", "Sad", "Hopeless", "Despair", "Cut", "Blood", and "Dark". If you see Abyss, it is best to ignore him, as he loathes human attention and will likely only depress you.

A dark setting where males look for females on a similar level of intoxication as them. There is often music playing. Upon entering the abyss one might start to grind with a random girl and then proceed to hook up with her. Ideally no names or words would be exchanged. It is very easy to get with many girls of low quality in one night. Due to the darkness and drunken state it is hard to judge the attractiveness of the females which can lead to mistakes. The abyss defines the saying quantity over quality.

P.S. Watch out for monsters.

Dude 1: Out of ten she was at best a 3, did you get her name?

Abyss is one of the few English words that derive from Sumerian, the world's first written language, which evolved some 5000 years ago in the lower Tigris and Euphrates Valley of what is now called Iraq. The word came into English in the late 14th century from the latin word abyssus, meaning "bottomless, the deep," but has been traced ultimately to the primordial sea that the Sumerians called the Abuzu.
